4 a) Introduction to Organic

A reaction in which one molecule adds to another without taking anything away, to form a single product.

Simplest whole-number ratio of the atoms present in a compound.

An atom or group of atoms that determine the chemical properties of a compound.

A series of compounds with similar chemical properties because they have the same functional group. Each member differs from the next by -CH2- and shows a gradation in physical properties.

Molecules containing carbon and hydrogen only.

A reaction in which an atom or a group of atoms in a molecule is replaced by a different atom or group of atoms.

A reaction in which a substance reacts with oxygen (burns) to form products and heat.

Formula that shows all the bonds in a molecule as individual lines and shows all atoms.

A formula applicable to all members of a homologous series.

Formula that shows how the atoms are joined together in a molecule written in a condensed form by omitting all the carbon-carbon and carbon-hydrogen single bonds.
